Structural Patterns

This work aims to study the crack pattern in masonry-like structures by a simplified description of the medium using a variational damage model. In literature, when modeling fractures in masonry structures, capturing both fracture types, cracks in units, and cracks at the interface simultaneously, usually requires a complicated scheme.

Structural and spatial patterns of tree species in forests are important indicators to explain which underlying mechanisms or processes regulating forest structure. In this article, techniques of spatial point pattern analysis were used to characterize structural and spatial patterns of two secondary rain forest stands in Cuc phuong National park, Vietnam.

The aim of the research was the processing of the vibration signatures from healthy and damaged composite beams acquired with the help of a Scanning Laser Vibrometer (SLV) upon excitation and analysis of the mode shapes acquired for damage detection. The displacement mode shapes acquired were then converted into curvature mode shapes with the help of a Central Difference Approximation method (CDA).

There were only limited researches on the properties of 3D periodic cellular materials, especially for 3D periodic cellular materials with Schwarz primitive structure which have potential to be used for energy absorption. The objective of this study is to investigate the energy absorption, compressive strength and deformation pattern of the 3D periodic cellular materials with Schwarz primitive structure, which possesses optimum bulk modulus. The study is planned to provide these important research issues of such 3D cellular materials for energy absorption applications.

This study uncovers a wide range of complex transport dynamics in transiently forced aquifers that has profound implications for the understanding and quantification of solute transport in these important groundwater systems. And the results in this thesis predict that complex transport structures and dynamics arise in natural transiently forced aquifers around the world. When such dynamics do arise, it will lead to mixing and reactive transport patterns that are very different from those predicted by conventional Darcy flow models.

South Western Anatolia is dominated by E-W and NW-SE trending active faults. The dip-slip Yatağan Fault is one of these active structures that trends in a NW direction for ~30 km. To assess the relative tectonic activity of the Yatağan Fault, two geomorphic segments were defined along the fault: the FS-1 (northern segment) and the FS-2 (southern segment). The vertical slip rate pattern of the fault was analyzed using steepness indexes, chi (χ) plots, and log-log slope area graphs.

The 2020 Samos, M7.0 earthquake was characterized by an unusual bi-modal-type distribution of damage: limited damage in the nearfield (especially northern Samos coast) and serious localized damage in multi-story buildings in the far field (İzmir area). This pattern is not consistent with the typical distribution of isoseismal lines, and it seems not to represent an isolated effect; the 2014 Samothraki- Gökçeada M6.9 earthquake, for example, may in fact represent a parallel, though at smaller scale.

In this report, SERS substrates based on Ag-decorated TiO2 nanofibers electrospun on a glass substrate (Ag/TiO2/glass) were successfully prepared using electrospinning and photodeposition methods. XRD pattern demonstrated that the crystalline structure of TiO2 nanofibers (TiO2 NFs) consisted of both anatase and rutile phase.

An examination of the first-row-transition-metal-doped boron clusters, B14M (M = Sc, Ti, V, Cr, Mn, Fe, Co, Ni, and Cu) in the neutral state, is carried out using DFT quantum chemical calculations. The lowest-energy equilibrium structures of the clusters considered are identified at the TPSSh/ 6- 311+G(d) level. The structural patterns of doped species evolve from exohedrally capped quasi-planar structure B14 to endohedrally doped double-ring tubular when M is from Sc to Cu.

Borotellurite glasses were prepared by melt quenching technique. Amorphous nature of samples was confirmed through X-ray diffraction (XRD) patterns. Effect of B2O3 content on the structure of glass network was studied through Fourier-transform infrared spectroscopy (FTIR) spectra. Optical band gap and Urbach energy were found from analysis of optical absorption spectra. Thermal studies were carried out by using Differential thermal analyzer (DTA) measurements.

Polypropylene/ maleic anhydride /organic montmorillonite nanocomposites (PP/ MA/ Org-MMT) have been prepared via direct melt intercalation in an internal mixer. Maleic anhydride (MA) was used as a compatibilizer to improve the dispersability of the clay. The structures of nanocomposites have been characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Mechanical properties and thermal stability were determined by tensile analysis and thermogravimetric analysis (TGA), respectively.

In this paper, we present the results of studying magnetic properties and magnetocaloric effect of Fe90-xPrxZr10 (x = 1, 2 and 3) rapidly quenched alloys. The alloy ribbons with thickness of about 15 µm were prepared by melt-spinning method on a single roller system. X-ray diffraction patterns of the ribbons manifest their almost amorphous structure. Thermomagnetization measurements show that the Curie temperature of the alloys can be controlled to be near room temperature by changing concentration of Pr (x).
